Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21262, here are decompositions:
- 41 + 21221 = 21262
- 71 + 21191 = 21262
- 83 + 21179 = 21262
- 113 + 21149 = 21262
- 173 + 21089 = 21262
- 239 + 21023 = 21262
- 251 + 21011 = 21262
- 281 + 20981 = 21262
Showing the first eight; more decompositions exist.
